Abstract
The invention discloses a corrosion-resistant injection molding material for automobiles, which comprises the following components in percentage by mass: 50% of polybutylene terephthalate, 40% of high-density polyethylene, and the balance of acrylonitrile-butadiene-styrene copolymers and unavoidable matters, wherein the polybutylene terephthalate contains 40% of glass additive type poly butylene tertephehalate. The corrosion-resistant injection molding material has acid and alkali corrosion resistance.
Description
Technical field
The present invention, relevant for a kind of Shooting Technique material, is particularly applied in the anticorrosive injectable plastic material in automotive industry.
Background technology
Complete processing molded or casting can large batch of acquisition same size part, so it has important effect in processing and manufacturing field.The development of developing same molding process of automotive industry is inseparable, and due to the component of the large batch of manufacture same size of automotive industry needs, so it relies on larger to molding process.
As the nonmetal parts part in automobile component, using injection molding process is the inevitable requirement of its Future Development at present.
Typical injection molding system comprises an injecting unit, a clamp assembly and a die assembly except other business.In injecting unit, starting material (for example PET pellet and analogue) pass through a funnel by feeding, and are heated by material tube heater, then are expelled in mould by nozzle.
Relative single technical background relative to material in metal-molding, as modern injection molding process, it adopts injectable plastic material to vary really, and improving and the injectable plastic material of the various performances of constantly bringing forth new ideas out along with polymer science and technology.
But because injectable plastic material is generally organic materials, so life-time service has self to degenerate or be subject to external interference and the danger that changes, be particularly applied in automotive industry and be applicable to the long-term outside work of automobile, have the working conditions such as Corrosive.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of injectable plastic material that is applicable to automotive industry, particularly a kind of erosion-resisting automobile injectable plastic material.
The invention provides a kind of anticorrosive automobile injectable plastic material, described injectable plastic material is molten state after heating and through injection moulding auto parts, each composition mass percent of described injectable plastic material is for this reason:
1) 50% polybutylene terephthalate, and in described polybutylene terephthalate, contain 40% glass additive type polybutylene terephthalate;
2) 40% high density polyethylene(HDPE);
3) all the other are acrylonitrile-butadiene-styrene copolymer and inevitable material.
Injectable plastic material in the present invention contains glass additive polybutylene terephthalate, has good chemical property, for customary acid alkaloid substance, all can effectively resist corrosion.
Embodiment
The invention provides a kind of anticorrosive automobile injectable plastic material, through the part of this material injection moulding, by the part being applied in automotive industry, and can resist daily chemical corrosion, physical abrasion.Common acid and alkali corrosion for example.
The invention provides a kind of anticorrosive automobile injectable plastic material, described injectable plastic material is molten state after heating and through injection moulding auto parts, each composition mass percent of described injectable plastic material is for this reason:
1) 50% polybutylene terephthalate, and in described polybutylene terephthalate, contain 40% glass additive type polybutylene terephthalate;
Polybutylene terephthalate (PBT) is those semi-crystalline materials, has extraordinary chemical stability and thermostability.Therefore temperature or chemical reagent have good erosion resistance to external world.Therefore under very wide envrionment conditions, there is good stability.
In PBT in the present invention simultaneously, contain 40% glass additive type polybutylene terephthalate, the absorption of this inorganics is stablized and safety its chemical property more, has improved corrosion resistance.
2) 40% high density polyethylene(HDPE);
It not only has good oxidation-resistance, after its moulding simultaneously, can have good permeability resistance, prevents the further infiltration of extraneous corrosive deposit.
3) all the other are acrylonitrile-butadiene-styrene copolymer and inevitable material.
As modified embodiment of the present invention, use the minimum cavity diameter in the injection moulding die cavity of described injectable plastic material to be greater than 12 millimeters.Be convenient to injection, filling and the moulding of injectable plastic material.
As another preferred modified embodiment of the present invention, this injectable plastic material also comprises 1 ~ 2% polycarbonate.It is conducive to the key that connects between current material, when whole intensity is provided, improves erosion resistance.
As an Application Example of the present invention, through the part of described injectable plastic material injection moulding, be air-conditioner air outlet.It can resist the variation of low temperature and high temperature, and the corrosion of air port air-flow.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claim provide, with and dependent claims.
